    Abstract: In the field of wastewater or effluent treatment, a method for treating wastewater includes a first step of treating carbon contained in the wastewater by means of oxygen, a second step of treating the nitrogen contained in the treated water at the end of the first step, a third step of determining a ratio between a concentration of carbon and a concentration of nitrogen in the water at the end of the first step, a fourth step of controlling the supply of oxygen necessary for the first step as a function of a difference between the determination carried out in the third step and a strictly positive setpoint of concentration ratio. A device implementing the method is also provided.

    Abstract: A computer-implemented method, computer program, and device for evaluating timed-based probabilities of failure of sections of a pipe network are provided. To do so, the pipe sections are clustered into classes based on structural and environmental parameters; within each class a sample of pipe sections are selected to be inspected. The scores that are obtained through the inspection are used to train a model of pipe conditions of pipes in a class, in order to estimate the pipe conditions of pipes that have not been inspected. The pipe conditions are used to parameterize a predictive model of pipe failures.

    Abstract: The present disclosure relates to the field of odor treatment. In particular, the disclosure relates to a method for managing a waste gas treatment device. The method includes the following steps: a step of taking into account gaseous pollutant concentration predictions at at least one point in a predefined geographical area; a step of comparing each predicted gaseous pollutant concentration at the at least one point of the predefined geographical area with a gaseous pollutant concentration reference value; a step of transmitting, to a control unit of a bypass air line of a waste gas treatment unit, a command to at least partially open the bypass air line when the result of the comparison indicates that at least one predicted gaseous pollutant concentration value is less than a gaseous pollutant concentration reference value.
